代码如下 | 复制代码 |
$a1 = array(array('blue','red','www.111cn.net'),array('black','pink','green')); $a2 = array('aaa','pink','bbbb'); $str = 'red'; $a2[] = $str; foreach($a1 as $key => $value) { $a1[$key] = array_diff($value,$a2); } print_r($a1); |
//更简单的做法
代码如下 | 复制代码 |
foreach (array_diff($a1, $a2) as $_key_1) { $arr_new[$_key_1] = $arr_1[$_key_1]; } |
/*
结果如下:
array
(
[0] => array
(
[0] => blue
[2] => yellow
)
[1] => array
(
[0] => black
[2] => green
)
)
array_diff语法
array array_diff ( array $array1 , array $array2 [, array $ ... ] )
对比较array1和array2返回差异。
*/
$array1 = array("a" => "green", "111cn.net", "blue", "red");
$array2 = array("b" => "green", "yellow", "red");
$result = array_diff($array1, $array2);
print_r($result);
/*
array
(
[1] => blue
)
